outer or free end of .eachZsleeve is provided I V with taperedthread asat 13 and each jofthe sleeves are slit axially a portion of the lengthof he; sleeve on the diametricallylopposed sides thereof as is indicatedat 14. a Mounted on the threaded end of each sleeve 11-, 12 is a thumbnut 15, engageable with the slit threaded end thereof. The diameter of Jof the sleeves and is horizontally movable with respect thereto,providing tWO'ZtdjUStf ments.- After thestem l6 has been properly 1adjusted, thezthumb nut 15 may be screwed I upon the tapered threads 13and by reason of the slit in the threaded portionv ofeach thereto.

A thumb nut 20, having its interior provided with taperedperipheral threads is adapted for engagement with the threaded end 18 ofthe head 17. A pair of supporting rods indicated generally at 21, 22,have stems 23, 24, extending through each sleeve of the T-shaped members17 'When the thumb nuts 20 on each sleeve are loose, thestems 23, 24,

- are rotatable and vertically adjustable inthe 10 sleeve. v

To fix the stems 23, 24, the thumb nut 20 is tightened upon the taperedthreads, thereby forcing the split end of the T-shaped members togetherand holding the stems in fixed relation. The lower ends of each part 21,22, is forked to provide oppositely disposed legs 25, 26, the continuityof which forms a V semi-circular support.

On the free ends of each leg 25, 26are formed a pair of inwardlyprojecting trunnions 27, 28, which .are rotatforked end flared inwardlyprovides avery comfortable and light bearing against the ears when thephones are in the listening position. I The ear phones 29 -29 areconnected witha suitable conductor wire 30, which leads to the devicebeing listened to, such'as a radio, a telephone or the like. Theearphones 29-29 may be of anyconventional type.

,It is to be understood that by describing in detail herein anyparticular form, structure or arrangement, it is not intended to limitthe invention beyond the terms of the several claims, for therequirements of the prior art.

What is'claimed is:

1. A supporting frame for earphonescomprising a-flatresilient metallicband of semicircular configuration, a pair of plates secured to the endsof the band and extending on the opposite sides at right angles thereto,a sleeve secured at its inner end to each end of the band and projectingat rightangles to the head of the user when the band is supportedthereon, each sleeve having a threaded yieldable portion on its freeend, a T-shaped member having a stem seated in and normally rotatableand horizontally movable with respect to the sleeve, means threadablyengageable with the yieldable end of the sleeve for selectively lockingthe stem with respect to theflsleeve, the head of the T-shapedmemberformed of a sleeve, having its upper end threaded and yieldable, a'pairof forked supports, stems on the forked supports rotatably andvertically movable in the sleeves of the T-shaped members, meanssupported on the yieldable ends of the last-mentioned sleeves forlocking the stems of the forked supports in selective position, theforked ends of the forked supports extending inwardly at an inclinationto a vertical plane, and a pair of ear phones rotatably mounted in theforked support.

' 2. A supporting frame for ear phones comprising a flat resilientmetallic band of semicircular configuration, a pair of plates securedtothe ends of the band and extending on the opposite sides at right anglesthereto, a sleeve secured at its inner end to each end of the band andprojecting at right angles to the head of the user when the band issupported thereon, each sleeve havinga threaded yieldable portion on itsfree end,xa T-shaped member having a stem seated in and normallyrotatable and horizontally movable with respect to the sleeve, meansthreadably engageable with the yieldable end of the sleeve forselectively locking the stem with respect to the sleeve, the head of theT-shaped member formed of a sleeve, having its upper end threaded and.yieldable, a pair of forked supports, stems on the forked'supportsrotatably and vertically movable in the'sleeves of the T-shaped members,means supported on the yieldable ends ofthe last-mentioned sleeves forlocking the stems of the forked supports in'selective position, theforked ends of the forked supports extending inwardly atan-inclinationto avertical plane, and a pair of ear phones rotatablymounted in the forked support, the radius ofsaid band being such as toterminate about the ears of the user.

3. In a supporting frame for ear phones comprising a fiat resili'entmetallic band of semi-circular configuration, a pair of plates securedto-the ends of the band and extending on the opposite sides-at right an-'gles thereto, asleeve secured at its inner end to each end of the bandand projecting at right angles to the head of the user when the band issupported thereon, each sleeve having a threaded yieldable portion onits free end, a T-shaped member having a stem seated in and normallyrotatable and horizontalmovable with respect to the sleeve, means treadably engageable with the yieldabl'e end of the sleeve forselectively locking the stem with respect to the sleeve, the head of theT-shaped member formed of a sleeve, having its upper end threaded andyieldable, a pair of forked supports, stems on the forked supportsrotatably and vertically movable in the sleeves of the T-shaped'members,means supported onthe yieldable ends of the last-mentionedsleeves forlocking the stems of the forked supports in selectiveposition, theforked ends of the forked supports extending inwardly at an inclinationto a vernate about the ears of the user, the head of the T-shaped membernormally disposed in a vertical position laterally of the ears of theuser.

i. A supporting frame for ear phones comprising an arcuate band, asleeve secured at one end to the band and having a threaded yieldableportionon its other end, a U-shaped member having a stem and normallyrotatably and longitudinally movable with respect to the sleeve, meansthreadedly engaged with the yieldable end of the sleeve for selectivelylocking the stem with respect to the sleeve,. the head ofthe U-shapedmember being in the form of a sleeve which has its upper end threadedand yieldable, an ear phone support having a stem extending through thelast mentioned sleeve and means supported on the yieldable end of thelast mentioned sleeve for locking the stem in selective position.
